| Astralloy 140 ksi is a fine-grained, general structural steel that yields a minimum tensile strength of 140 ksi (960 MPa). This high-strength alloy plate achieves its mechanical properties by being water quenched and tempered. This structural alloy provides the opportunity to reduce component weight by offering a high strength to weight ratio along with improved ductility. It is formable and weldable when following good shop practice and has a service temperature which ranges from -50°F (-46°C) to 800°F. Astralloy 140 ksi is optimal for use in mining equipment, forestry (427°C) equipment, construction equipment, structural steel works, raw material handling, quarries, shredders, crushers, forestry equipment, cranes, buckets, blades, bridges, shears, booms, hoists, and transport trailers. Each manufacturing mill has its own proprietary chemical composition and heat-treating process.Information provided by Astralloy, a Nucor Company. |
